I'm looking for this BL Manga :

Actor (/ex-actor) Seme × Politician Uke [they were classmates in highschool]. Uke is living with his dad's illegitimate child and seme shows up suddenly one day. Three starts living together and eventually get married as a part of Uke's father's political scheme (when uke gets taken picture of, by a a paparazzi when Seme jokingly kissed uke) to create a sob story about his "gay" son, gain popularity from the younger generation as he promises gay marriage legalisation (to win the election). Is turns out both had crush on each other.
